Tomi/Z whmn it nez concern:

-Be itknown that I, WIL I M F. C NKLIN,

a resident ofLeechburg, in {the countyf of Armstrong and State of Pennsylvania, have invented a new and useful Improvement in Metal Coiling and Straightening Apparatus; and I do hereby declare the following to be a full, clear, and exact description thereof.

My inventionrelates to apparatus for coiling and straightening, stretching, or drawing.

the rolls or dies or receiving the same from driven rolls, as may be desired; 1 By this apparatusI am enabled to grip the strips and at the same time expand areel on which the strip is coiled, to control the coiling-operation, keeping the material in perfect aline-' ment and holding the strip as coiled under tension and pressure, and to hold the material in coil until it is clamped orbound together ready to be released from the reel;

The special improvements embodied in the invention include the combination, with metal-reducing devices, rolls, or dies, of a ower-driven ex'pansible reel having a clamp or engaging the strip and so drawing it under tension as it is wound upon the'reel. 1

It also includes certain improvements in the construction of the reel'and the clamping device by which they both can be operated by' a single motion. 7 v

It also consists in pressure'device's operating the strip as reeled toihold it to place as it;

is coiled.

It also consists in certain lever and clutch connections for controlling the movable parts and in certain other improvements, all of which willbe herenafter'd'escribed and i claimed.

To enable othersskilled in the art to make and use .my' invention, I will describe the same more fully, referring to the accompanying drawings, in which Figure 1 is a sideview, partly in section;

Fig. 3 is a cross-section on the line 3 3, Fig.1..

Fig. 4 is a longitudinal section of the. reel.

The'apparatus is supported upon asuitable base or frame 1, having bearings 23, in

which is mounted themain shaft 4, carrying? This reel may of- 7 at one end the reel 5.

course be driven by any suitable power connection. The apparatus illustrated is found,

however, the most desirable, and I will therefore describe. the same. 7

upon the main shaft 4 is the driving-Wheel. 6,"

Mounted loosely driven by any suitable power and having the I clutch-face 7, formed on the inner side of its rim 8. Sup orted on the bed-frame 1 isthe stationary c utch face ormember 9, the same being formed of a frame 10, secured to and extending up from the mainframe 1 and havl ing a bearing 11, fitting around the main shaft 4 tohold the stationary clutch member in proper line. Between .the clutch-member 7 and the clutch member 9 is mounted thesliding clutch 12, which has a feather-andgroove connection-13 with the'main shaft 4 and is provided with the clutch face 14, en

gaging withthe clutch-face? of the drivin Wheel 6 and the clutch-face 15, engaging Wit the stationary clutch member 9. This mechanism provides for the quick rotation of e the reel 5, carried on the main shaft.-that is,

as soon as the stri to be drawn is connected therewith-and a so for the quick stoppin of the'reelas soon as the strip is woun thereon, so that the reel is under practically perfect control.

The sliding lutch member 12 is operated through a sultable lever 16, engaging with a collar 17 and controlled by'the'treadl'e 18,

which has'a tog le-lever connection 19 with the lever 16, the ever 16 carrying the weight 21' to throw the clutch from connection with the driving-wheel 6 into the .stationa clutch member g When' the treadle 18'1s raised.- The treadle 18 is'rigidly secured to the'shaft 22, which also has ri idly 'secured thereto the toggle-arm 20, an -the 'treadle I osition by. means of the spring-catch 24. heapparae may be locked in itslowest tus also providesfor the control of the coiling of the strip throu h'the friction-clutch connection with the. riv'ing-wheel '6. The togolpposite thereto.

' 5 it; is removed from'the reel.

1 to apply the necessary pressure to the strip to coil or wind it under tension, the operation of which leads to the straightening or stretching of the strip, while, if necessary, sufficient power can be applied to draw the strip under tension through the reducing rolls or dies, the

necessary 'power for drawing and finishing the strip being thus provided. The app drawin s,-and I will now describe the same.

The ree 5 is carried on the end of the main shaft 4 and has the hub or spider 25, the inner disk or plate 26, and the outer disk or front plate 27, and between these disks the expansible reel-sections 32 and 33, the reelsection 32 being secured by bolting to the disks 26 and 27. The disks are also -secured to the hub or spider 25. ner and outer plates 26 27 is the cam-bar 28, which can be turned by a suitable removable 3o hand-crank 29, this cam-bar having, as illustrated, the eccentric clamping-face 30'along one edge and the cam-face 31 along the edge The winding. portion of e reel 5 is formed in two sections, the reel 3 5 section 32 being rigid with the main reel-body and clamped between the inner and outer plates 26 27, while the reel-section 33 is mounted to slide between said inner and outer plates, and so provides for expanding and collapsing the reel. The reel-sect ons 32 and 33 are each provided with recesses at their ends, which together form the recesses 34,'providing for the binding of the coiled strip or-rod by suitable clamps or clips before The stationary section 32 ha' s'also the slot 35 for the entrance of the end of the strip or rod, as illustrated at 36, and within the said slot 35 and opposite the clamp-face 30 of the cam 28 is the bearing face 37 the end of the strip being clamped between said face and the clamping-face 30 of.

the cam, as illustrated.

The sliding reel-section 33 is preferably mounted as follows: On opposite sides of the hub 25 are formed guideways 38, and the reel-section 33 has the guide-arms fitting in the guideways, these guide-arms being connected above men the opposite side of the hub from the. main body of said reel-section 6o 33 by the plate 40, upon which the cam-face 31 v of" the cam 28 bears, as illustrated. A spnn 41 is interposed between said plate 40 andt e hub 25, which operates to raise the reel-section 33 and so collapse the reel and holds it in such position, except when oper ara tus for such purpose is illustrated in the- Mounted in the inated upon by the cam 28. The turning of said cam 28 therefore serves the double function of clamping the strip in the reel between the eccentric face 30 of the cam-bar 2S and the clamping-face 37 of the reel-section 32 and expanding the reel through the ca1n-face 31, bearing upon the plate 40.

In the operation of reeling the strips it is desirable, as above stated, to hold the strip under compression during reeling and to bind it firmly in place until it may be bound by suitable clips and so held ready for removal from the reel. To accomplish this, I

provide the lever42, carrying at its end the roller 43, adapted to contact with the strip being coiled, the lever and its roller being held in contact by means of the spring 44, connecting with the short arm of the lever 42 by means of a rod 45. The spring 44 is held in a suitable yoke 46, secured to the bedframe 1, and is withdrawn'by means of the treadle 47 and connecting-rod 48, said treadle being held inits lowest or withdrawn position by means of the spring-catch 49. It is desir able in the operation of such reeling mechanism to hold the reel in position for receivin the strip as it comes from the rolls or dies, an

for that purpose I form in the edge of the inner disk 26 of the reel-body the notch 50, with which a spring-pawl or stop-catch 51 mounted on the' main frame at 52, engages. De-

pending from this catch is the yoke 53, which, i

as shown,fits around the treadle 18, operating the clutch mechanism, this yoke eing of such size that when the treadle 18 is depressed to connect the clutch with the driv ing-wheel 6 the base of the treadle first engages with the base of the yoke 53 and. withdraws the catch 51, leaving the reel free to turn; but, as soon as the treadle 18 is raised and the weight 20 caused to throw the clutch into-engagement with the stationary clutch 9 this stop-catch 51 is free to act, andit engages.

with the notch 50 of the reel and so holds the reel in the proper position for receiving the next strip. The spring-catches and 49 are of the. same construction and on the same line, and the spring-catch 24 (shown in Fig. 1) is intended to engage with the treadle 18, which in said figure is shown in its raised position. I

When the apparatus above described is employed in the reeling of strips, its operation is as follows: The operation eing practically the same in thereeling of wire rods, thou h, if desired, suitable mechanism for gui ing the coiling'of the rod upon the reel maybe employed, the strip 36, either fed by power or drauni througi the rolls 54 or through dies 55, (illustrated diaammatieally in dotted lines,) is inserted into the slot 35 of the reel, and by turning the cam 28 the strip is clamped to the reel and the reel expanded, as illustrated in Figs. 3 t0 5. The treadle 18 is then forced downwardly, throwing the clutch member 12 intoreel under ressure of the spring mec anism a by the sli I 44. The epression of the treadle 18 also withdraws the pawl or stop 51 from the notch 50, leavin the reel free toturn. The s eed of the rec is such that it acts to win the strip under tension or to draw it through the dies, the drawing strain being regulated ac-' cording to the material operated uponand of the friction-clutch and the material uring coiling being compressed against the-reel bythe spring-roller 43. .As

soon as the stri is drawn entirely from the rolls or dies an entirely coiled upon there'el I the'treadle 18 is released, when throughthe weights 20 operating on the clutchdever -16 the clutch is thrown into contact with the stationary clutch member. 9, stopping the rotation of the. reel, and'thishsame movement frees the stop-catch 51, which en a es with the notch in the rim of .the rec are reel. being thus stopped in proper position for the reelin of the next strip. After the strip is reele and to prevent -the u'ncoiling thereof, the pressure-roller 43 isheld in con-v tact with the coiledstrip until the operator can insert suitable metal clamps-or'clips 56 through the recesses'34 of-the reeland bind the coil by means of the same, after which the treadle 47 is depressed, withdrawing said ressure-roller from contact with the rolls.

n order to release the coil, it is then only necessary to turn the cam 28, mounted in the reel-body, which releases the forward end ofthe strip, and at'the same time through the :pring 41 the movable reel-section 33 is.

awn toward the stationary section 32, thus .collapsing the reel and leaving the coil free to I be withdrawn therefrom. 'The several operations can be quickly performed by a workman standing at the'side of the reel ready to both operate the cam 28 and the differentlevers, as above described.

The apparatus has been found valuable for v the reeling of thin metal strips, rods, or wire and to work effie'iently and rapidly; It is of special. advantage in straightening, coiling,

and "flattening thin metal strips delivered from. dies rolls, slitting-machines, 1&0. as in addition to coiling the same under tension "and in that way insuring a perfectl straight strip, it keeps the material in per ect aline- .ment while passing through the rolls or other machines and winding u on the'reel under f tension, so insuring a per ectly straight strip, 60

no matter what its len th maybe, and dispensing with the necessity of stretching-machines for straightening the material a ter it has been rolled, slit, or flattened. The ten-.'

sion upon the metal can be regulated at will through the adjustment of the friction-elutch' A I I mechanism, and the strip as delivered held ti htly coiled untilit can'be clamped ready or withdrawal from the ap aratus,

while the a paratus is automatically rought to and hel in proper position for receiving the-strips.
